I bought two of these totally hackable current meters: https://www.conrad.de/de/energiekosten-messgeraet-basetech-em-2000-integrierte-kindersicherung-1302517.html at the mini maker faire in Berlin that is this weekend, heavily sponsored by Conrad Electronics. Probably the best about the whole mini maker faire :D @al1 was there too, so that was nice :) We laughed about the whole "wanting to be a big event" feeling, sadly there weren't many visitors around. We've met some cool people though and talked a bit and got two or three ideas for new projects. There was also no lottery to win a DJI spark. That would have been cool, without much competition.
